lla it known that I, (lin-iam# lmsiz, n

citizen of thv United States, iwi-lin ut` Saloni, in tho county of Essexund m inonwcalth of .\lus-'a liu.-ctts, havo invented curtainlniprovunients in liurnishing-L'Iuchinos, of whit-h the followingdescription, in roniu'otion with the aouonipanying drawings, is aspecification. like refcniice chara ti-r.- on thu dra wings indicatinglike parts in the sew-ral ligurrs.

Thixl invention relatos to machines for linis'hing loatlirr andpurticularl to ma chinos :ula itt-il for use in linisliin" the surfarvsof tir hrrls :unl solo of lioots and shops.

'l`hc ohjot of thc invention is particularly to improv(- tlioconatrurtioiil of the huruishing or other finishing tools used inmachines of this class and to provide an improved rest having capacityfor adjustuil-nt to ciiahhe heels varying in shape to lio .properlysnppoited thereby iii position' to be artcd upon hv tlu saine tool.

.\n inmorlant feature of thc invention conuists in a hurnishin r orother finishing. tool, comprising a rarricr and a plurality l-f workmembers forming the working facc of thil tool. in which tlil workmembers un. yieldingly mounted und artI normally held in positio'n toform a rvgular or uniformworking l'uve for tlic'too iidtii'itliatiininvariations or lark of uniformity in tlioyiel ing Supporting moan.

l'n tho embodiment of the invention herein illustrati-d tlio workmembers, which are ahown as having rvlatcly long acting faces t-xtondingari-os tho working face of thc lutrni-hing tool and collectively fortuin--iuh working favo, arcl pivotnlly connecte( to loaf spring-h which tcudnormally to tluuoil.' uwmln'rn are provided with mctm coat-ting willilixml int-ans on tho carrier for limiting tlu- |\'tint to whirh tlnlwork mtimlu-r.- aro pressi-l outwardly liy the. springs and :it-o fordetermining thv angular posilinli of lliov il'l\' liullllit'l'`t't'li|ll\'('l t0 tlltfll |i\ot.-. rr ayonrutrly .shaping aid two oo-:u'ting liu-ana tluwork Inonilu-rh will lit! litltl n regular'or uniformworking face irrespective of variations in the shape or strength of thesprings, due, for example, to warning or twisting 'of the springs,uneven tt uipering, or changes in the shape of the springs during uae'.

A nother very important feature of the invczition is that, in theconstruction herein shown. the work members aro supported so that theymay rock or tip with relationto their sustaining means, whereby theworking face of thc tool may coliform to the sui*- facc of the workpresented to it, as, for instance, if the contour of the work isditlerent from that ofthe workin face; and also, if the work is sopresent as to engage ai one edge of the working face, the w members maytip and, aa rein shown, also yield, so as to conform to the ition aswell aa the contour of the work and therefore engage the work with theentire width of the workin face of the tool.

The invention is herein shown as embodiedjin a machine comprising arotary burnialiing tool having the working fam on the circumference ofthe tool; but the invention is obviously not limited to this form oftool, and sonic features of the invention also nia be employed toadv-intage in tools intended for other purposes than burnishing and anau, una. D

Still another feature of the invention il an im roved work neat adaptedto be ao adjust as to assist the operator in properl presenti the worktothe bumishin too Other eaturca of the invention inc udmg certaindetails o! construction an combinations of parts, will bc hereinafterdescribed and pointed out in tlio claims.

The invention is herein shown as embodied in a machine adapted forburnishing or finishin the edges of heeis of boots and shoes. he machinecomprises a frame l, a portion only of, which is shown in Fi 1 und 2,the frame having bearings 2 or7 a sliuft`4 upon which the burnishiii vtool is secured for rotation therewith. 'ihe burnishingtool is shown ascom rising a carrier hereinafter more fu ly described, said carrierbeing in the form of a sleev adapted to tit on a reduced portion 6 o1the shaft 4. The reduced portion of the shaft is provided between itsends with slots 8, which, as shown, do not extend to the end of theshaft, and with a ntral, longitudinal bore comprising a screw-threadedportion 10 and a smooth rtion 12 of less diameter than the threa edportion. A bolt having a screwthreaded portion 14 and a tapering endportion 16 is adapted to be, screwed into the bore, its tapered portion16 engagin the shoulder formed at the outer end o the portion 12, andthereby ,expanding the slotted rtion of the shaftto cause it to engagehe carrier 5 frictionall for firmly securing and accurately centeringthe burnishin tool on the shaft. B locating the, slots 8 tween pointswithin t e ends of the shaft as shown the enlargement of the shaftproduced by the expandingalevice is greatest approximately midway tweenthe ends of'the ,slotted portion of the shaft, instead' of at its end,as would be the case id the slots extend ,to the end of the sha Byreason of the present construction the teol is more accumtely centeredand more firmly held in position than would be the case if the ex ansionof the shaft were greatest at the ens of the shaft.

The burnisliing tool here shown as ein: bodyiiig the invention comrises, besides the carrier 5 above mentions a plurality! of worlrmembers 20 which are mounted on the carrier for rotation therewith. Thework members are so connected to the carrier as to be capable of'movement inwardly 'and outwardly relative to the carrier and also tohave other movements iis will be described. .Thepovlvtoi: memlersf areheroin s own as sup upon ea sprin 22, ailthough of course they might beyielisn fly supported by other means if desired. lit i these' ends inviewv the carrier' is formed with a portion 24 of relatively largediameter, a reduced rtion 26, and a flan ed outer end 28. e portion 24is provi ed 'th longitudinal ves 30 separated by ribs 32, see Fig. 8, te grooves forming seats in which the rear portions of the springs 22 fitsnugly, while the rils hold the s rin securely a inst lateral movement,at is movement in the direction of the width of the springs. Clampingbolts 34 extending.

througllli the springs and into the carrier bind e springs tirmly inplace within the grooves 30.

In accordance with the present invention the work members are movablymounted on the springs 22 and to this end the sprin are each providediieai their free, front en with outstanding ears 40, which, as here'iishown, are formed on a clip 42 secured to the s ring. Between the ears40 is arran the oot 44 of a work member 20, which, as

shown, is connected to the ears by means of a pivot pin 46. The workmembers may, lhoweverz be mounted on the springs in any other suitablemanner which will permit of a rocking or tipping movement of the workmembers.

The angular position of the work members with relation to the pivots 46,or with rela tion to the springs 22, is determined by providing the feet44 of the work members with forwardly and backwailiv extending lugs 48,49 w ich are ,iirran for en l'agement witli positioning means sup rt ythe carrier. As shown, a sleeve is arra outside the carrier and issecured thereto by screws 53 which pass'tlirou h a flange 52 of thesleeve inte 'the rear end thus be seen that said sleeve and lip formpositioning means which by en ment with the work members determines t enoriniil position of said members, and by insuring a uniform normalposition for the several work members insures a liar and even workinface for the tool. t will also be unders that the springs serve to holdthe work `nieiiibers yieldiiigly outwardly .ii ainst saidpositioninineans, but permit tie work members to forced inwardl' towardthe carrier by, pressure of the wor of the carrier ,as illustrated inFig. 2. The front end of the end 28 of the carlll against the workingface of the tool; The u movable connection .formed by thol iivot 46between each work member and its supporting spring also permits eachwork member to rock' or tip against the pres sure of the s ring, asshown on the lower side of ig. 5, while the elasticity of the springenables each work niember to tip-slghtly in n direction at right anglesto the irection of its movement about the pivot 46. This capacity of thework ti and having specifically described a conction the severalfeatures thereof in a pre erred form, I claim as new and desire tosecure by Letters Patent in the United States 1.
